Water Runoff Diagram
The infiltration and runoff of rainwater is directly influenced by the amount of impervious surface in an area. This diagram shows five types of terrain. On woods and meadows with an impervious surface of 0%, expect about 0.6 inches of runoff with 2.5 inches of infiltration. On row crop agriculture, with an impervious surface of 0%, expect about 1 inch of runoff with 2 inches of infiltration. On residential terrain such as 0.25 acre lots with an impervious surface of 38%, expect about 1.6 inches of runoff and 1.4 inches of infiltration. In an urban business district with impervious surface of 85%, expect about 2.5 inches of runoff and 0.5 inches of infiltration.
Soil Food Web Diagram
This diagram shows a visual representation of the soil food web. The top level includes a tree, which collects solar energy, carbon dioxide, and nutrients, creating organic matter in the form of leaves. This matter is then processed by primary consumers, including fungi and bacteria. The next level features secondary consumers, including protozoa, springtails, nematodes, and mites. Finally, the bottom layer features higher-level consumers, including earthworms, ground beetles, millipedes, centipedes, ants, and spiders.
Soil Structure Diagram
This diagram shows three types of soil. Healthy soil exhibits a varied structure, with both large and small particles. Sandy soil exhibits a structure composed entirely of all small particles. Compacted soil exhibits a structure composed of long, flat particles in dense layers.
Soil pH Diagram
This diagram shows a range of pH levels, beginning with pH 3 on the far left (acidity) and ending in pH 10 on the far right (alkalinity). The color gradient changes from red (acidic) on the left to blue (alkaline) on the right. The middle area is denoted as neutral. According to the chart, mineral soils in arid regions fall between pH 7 and pH 9 (neutral to moderately alkaline). Mineral soils in humid regions fall between pH 7 and pH 5 (neutral to moderately acidic). Acidic peats fall in the pH 3 to 4 range. Highly alkaline soils have a pH of 10 or higher.
Soil Type and Composition Diagram
This diagram shows soil types in a triangle format. The bottom edge of the triangle shows a range of percent sand, from zero to 100. The right side of the triangle shows a range of percent silt, from zero to 100. The left side of the triangle shows a range of percent clay, from zero to 100. The top corner (furthest from bottom) represents clay soil. The middle of the triangle represents sandy clay (upper middle left), sandy clay loam (lower middle left) clay loam (upper middle center), loam (lower middle center) silty clay (upper middle right), and silty clay loam (lower middle right). The bottom of the triangle represents sand (bottom far left), loamy sand and sandy loam (bottom left), silt loam (bottom right), and silt (bottom far right).
Composting Diagram
This diagram shows an illustration of a compost pile with the following layers from bottom to top: wood chips, green leaves, brown leaves, grass clippings, straw, kitchen scraps, and brown leaves.
